How does it work?
Pain is an electrical signal that travels along nerve fibers through the spinal cord to the brain.
PeaceHealth Southwest's pain specialists use the Precision Plus System to mask these pain signals. The system delivers tiny doses of electricity to change the pain signal into something your brain interprets as a pleasant sensation called paresthesia. Patients describe paresthesia as feeling like a gentle tingling or massage.

The graphic on the left shows you how spinal cord stimulation works:
- Pain signals travel along the spinal cord toward the brain.
- A small rechargeable implantable pulse generator (IPG) produces tiny electrical impulses.
The impulses travel along one or two small wires called leads, which are attached to the implant. Each lead has tightly spaced electrode contacts.
- Electrode contacts deliver electrical impulses to a specific location on the spinal cord to mask the pain signals.
- The masked signals then travel to the brain where they are often perceived (felt) as tingling sensations (paresthesia), and the feeling of pain is reduced.
